I have attached a macro shot of the panellus stipticus mycellium showing classic linear growth through the fermented alder sawdust. The spot you see here is one of the largest, yet less than a 3/4" across today, the 4th day since inoculation. Although slow, it seems to be growing fine. The speed doesn't bother me at all, though, since the last time I grew bags out, I believe full colonization took 6 weeks, with a 4th week substrate mixing through the bag. As far as I know this speed is normal for this species; after all, not everything grows super fast like oysters do - most mushrooms don't and many species in nature take a whole year or longer to prepare for a brief fruiting cycle, sometimes as short as a single week. Fortunately while stipticus mycelium grows slowly, the fruits also mature very slowly. Last grow I had fruits that lasted over a month without much degradation and they were still glowing strong. Even after picking them, they
glowed for days!

PS - I am inoculating three more bags tomorrow with roughly the same pH, 4.6. I will bring a bag into the noise bridge once colonization is close to done, maybe after the 4-week mix of the substrate.
